Micropsammis Mielke, 1975 (Family Pseudotachidiidae)
Mielke (1975: 40) established this genus for two new species, Micropsammis noodti Mielke, 1975 and M. secunda Mielke, 1975 but neglected to fix a type species, rendering the generic name Micropsammis unavailable. Gee and Huys (1991: 1154) proposed a new genus Telopsammis for M. secunda and inadvertently made the generic name Micropsammis available by designating M. noodti as the type species (p. 1146) and by providing an amended generic diagnosis (p. 1145) (ICZN Arts 13.1.1 and 13.3). Huys et al. (1996), Willen (2000) and Boxshall and Halsey (2004) continued to credit Mielke (1975) with the authorship but based on the type fixation the genus should be cited as Micropsammis Gee & Huys, 1991 with the new combination, Micropsammis noodti (Mielke, 1975), as the type and only originally included species. Mielke (1997) argued against the recognition of the genus Telopsammis but his opinion appears to have gathered no support (Willen 2000; Boxshall & Halsey 2004; Wells 2007; Kornev & Chertoprud 2008). Five out of seven synapomorphies shared by Telopsammis and Leptotachidia Becker, 1974 [characters (2)–(5) and (7) identified by Gee and Huys (1991: 1153)] are also displayed by Micropsammis galapagoensis Mielke, 1997, and this suggests it cannot be maintained in Micropsammis. It is here tentatively removed to Telopsammis as T. galapagoensis (Mielke, 1997) comb. nov. A third species, Telopsammis pelobionta, was recently described by Kornev and Chertoprud (2008: 183).[details]
